English to Spanish Tech/Engineering Engineering (general) rubber boot

Buenos días,

Espero que puedan ayudarme con una expresión al español: “rubber boot”, relacionada con el transductor TOCO de un monitor materno-fetal. Muchas gracias:

“Place the TOCO transducer on a solid surface with the rubber surface uppermost and level. Press the touchscreen on the Toco area for 1 second to zero it (10%).

With the rubber surface still uppermost and level, place a 100g weight in the centre of the boot. (The shape of this weight is important and the contact area on the rubber boot should be 12mm diameter maximum).”
